61、轴箱CAD方面开始研究。尤其是进入90年代以来，随着计算机技术的发展，交互式绘图和数据库管理系统等的发展和应用，使组合机床CAD技术日益实用且使用范围不断扩大，发达国家在组合机床设计中已普遍采用了CAD技术。目前，正在向CAD/CAM集成系统发展。近年来，据我们对美国几个主要机床厂家(BURGMAST、KINGSBURY、INGERSOLL LAMB、CINCINNATI、MILACRON、CROSS等公司)的了解，其CAD技术已得到普遍应用。其中最引人注目的是INGERSOLL公司具有50个交互式CAD工作站组成的软、硬件环境，使其实现了几乎百分之百的CAD化。国内对组合机床设计采用CAD的

62、认识也比较早。70年代初，大连组合机床研究所就开始了这方面的研究工作。1978年国家把组合机床CAD列为机械工业重点项目，并责成上海交通大学、大连组合机床研究所、机械部自动化研究所负责，大连理工大学、清华大学、北京工业大学、上海机电产品研究院等单位参加，对钻孔组合机床CAD进行了研究，从此揭开了我国组合机床CAD技术的序幕。经过十多年的努力，取得了初步成果。但是，组合机床CAD系统是在VAX-750和Micro VAX上开发的，硬件投资大，不易于推广应用。受当时硬件条件及软件环境的限制，软件适用范围窄，用户使用不方便。3开发组合机床CAD系统专用软件CAD技术是当代电子信息技术的重要组成部分，

63、CAD技术商品化应作为高新技术产业中重中之重。在支撑软件和硬件的基础上，针对不同行业、不同专业进行软件二次开发，开发出适合本行业、本专业的专用商品化软件，不仅可以取得良好的经济效益，而且会取得重大的社会效益。“九五”期间国家把汽车工业作为国民经济的支柱产业，给汽车工业提供技术装备的组合机床行业得以迅速发展。随着汽车工业的发展，提高组合机床设计质量、缩短设计周期便成为极其迫切的任务。采用组合机床CAD技术，能缩短设计周期，提高产品设计质量，提高企业在行业中的竞争力，给企业带来显著的经济效益。大连是我国重要的工业基地，作为组合机床行业科技开发中心的大连组合机床研究所，应当发挥行业的主导作用，为实现

64、设计自动化、增强企业技术创新能力和产品竞争能力，推动我国组合机床设计水平，尽快向组合机床行业厂提供功能强、操作灵活、界面友好、技术含量高的组合机床CAD软件。4开发软件的技术基础随着微电子技术的发展，微机的性能有了很大的提高。现在P已经主导市场，P开始上市，其CPU性能指标已接近几年前的工作站指标。国外CAD软件向微机的Window95/98、Windows NT上移植，如Pro/Engineer、-DEAS、CADDS5等。微机的图形加速卡性能在提高，基本上能进行实体的移动和旋转。微机CAD是一个发展方向，相应的硬件比工作站要降低很多。经过几年的努力，我们利用Windows的SDK软件开发技

65、术、Windows环境下多进程间的动态数据交换技术(DDE)、数据库操作技术(ODBC)、图形软件二次开发技术及目标链接与嵌入技术(OLE)，开发了集通用机械CAD和组合机床CAD于一体的CAD集成系统。5组合机床CAD系统软件组合机床CAD系统软件采用C语言，在Windows环境下开发的面向组合机床设计人员的参数化图形信息管理系统。数据库系统用C语言独立编写，本软件融数据库操作系统和参数化图形系统于一体，形成功能强大的参数化图形信息管理系统。组合机床CAD系统包括组合机床夹具CAD系统、组合机床自动线方案三维图形CAD系统、组合机床总图CAD系统、组合机床加工示意图CAD系统和组合机床多轴箱CAD系统。5.1组合机床夹具CAD系统利用机械CAD参数化图形信息管理技术和交互设计方法，开发组合机床夹具CAD系统，其适用面广、实用性强、推广应用前景广阔。组合机床夹具CAD系统按照其主要功能可分为四大模块：定位支撑系统CAD系统、夹紧机构CAD系统、导向装置CAD系统和典型夹具夹紧力的计算机辅助分析与计算。5.1.1定位支撑系统CAD系统定位支撑系统主要由定位支撑、辅助支撑和限位元件组成。定位支撑是指
